|The Haze app is designed to measure the Haze percentage of transparent and translucent samples. It provides both Haze % and CIE Lab color values as outputs. The app utilizes two methods, namely Total Transmission and Diffuse Transmission, to determine the Haze value.
The Total Transmission method measures the total amount of light transmitted through the sample, including both direct and scattered light. The Diffuse Transmission method specifically quantifies the scattered light component. By comparing these two measurements, the app calculates the Haze percentage, which represents the degree of light scattering within the sample.
The App Settings section includes four buttons, each represented by a pictorial icon that corresponds to the step-by-step process of measuring Haze. These intuitive icons guide users through the sequential steps required to measure Haze accurately and efficiently.
“Transmission Reference”: This button signifies the first step, where users are required to take a transmission reference measurement. This establishes a baseline for the measurement by capturing the transmission of light through a reference material or a clear sample.
“Total Transmission”: The second button represents the step to measure the total transmission of the sample. Users need to place the sample in the measurement setup and capture the total transmission of light passing through it.
“Diffuse Transmission Reference”: The third button indicates the process of capturing the diffuse transmission reference. This step involves taking measurements of scattered or diffused light using a reference material or a specially designed setup.
“Calculate Haze“: The fourth button represents the final step, where users place the sample again in the measurement setup. By using the previously acquired transmission and diffuse transmission reference measurements, the app calculates the Haze percentage of the sample, providing the final result.
The Step-by-Step Guide, accessible under the Info icon , provides detailed instructions on how to configure the sphere setup for each step of the Haze measurement process. This guide assists users in properly setting up the measurement apparatus to ensure accurate and reliable results.
The app automatically saves the transmission and diffuses reference measurements for future use, eliminating the need for users to repeat these steps each time they perform a measurement. Once the transmission reference and diffuse reference measurements are taken, the app stores the data in its memory or a designated location. This allows users to conveniently access and utilize the previously acquired references when performing subsequent Haze measurements. By eliminating the need for repeated reference measurements, the app streamlines the measurement process, saving time and ensuring consistent and accurate Haze calculations.
The Haze app features four separate graph windows, each representing and plotting the data for a specific step of the Haze measurement process, the app provides a dedicated graph window for each step, offering a clear and focused visualization of the data.
The Data window in the Haze app focuses on providing a comprehensive overview of the average haze level across the spectral range. This information allows users to evaluate the overall haze or opacity of the sample. This window also provides the color representation of the sample. This can be in the form of CIE Lab color values or other color models, allowing users to understand the color properties of the sample in conjunction with the haze measurement. The color information enhances the characterization of the sample’s appearance, providing insights into its translucency and hue.
